Power requirements
Each unit in the sonar room should be provided with a separate circuit breaker on the
mains supply.
Proper vessel ground must be provided.
A minimum number of additional electrical outlets must be provided for other equipment.
Cabling requirements
The sonar room units are connected to other EM 2040 MKII units located in different
compartments on the vessel. The units may also be connected to peripheral devices. If
these cables pass through hatches or areas where they may be damaged, they must be
run in conduits. Minimum 2” conduit is recommended.
Make sure that all system cables are properly connected and secured, and installed
with some slack. The slack is essential to withstand vibrations, and to facilitate future
maintenance and replacements.
